MCQ
In given circuit, voltage across the inductor will be .....$V$
- A$40$
- B$60$
- ✓$80$
- D$100$
✓
Answer
Correct option: C.
$80$
c
$\mathrm{V}_{\mathrm{rms}}=\frac{100 \sqrt{2}}{\sqrt{2}}=100 \mathrm{\,volt}$
$\mathrm{V}_{\mathrm{rms}}=\frac{100 \sqrt{2}}{\sqrt{2}}=100 \mathrm{\,volt}$
$\mathrm{V}_{\mathrm{RMS}}^{2}=\mathrm{V}_{\mathrm{R}}^{2}+\mathrm{V}_{\mathrm{L}}^{2}$
$\Rightarrow \mathrm{V}_{\mathrm{L}}^{2}=(100)^{2}-(60)^{2}$
$=6400$
$\mathrm{V}_{\mathrm{L}}=80 \mathrm{\,volt}$
